Barack Obama's new campaign ad – video

Barack Obama's re-election campaign has unveiled a short film with a new slogan: 'Forward'. The seven-minute video begins by recalling the stock market crash of 2008, and revisits the end of the war in Iraq and the death of Osama bin Laden. Obama defends his first term and criticises the Tea Party movement. The video will be shown at Obama's first two big campaign rallies in Ohio and Virginia this weekend
